Abstract
BACKGROUND Vascular complications (VCs) still represent one of the principal concerns of trans-femoral trans-catheter aortic valve replacement (TF-TAVR). New-generation devices can minimize such complications but the arterial access management is left to the operator's choice. This study aims to describe the rate of VCs in a contemporary cohort of patients undergoing TAVR with new-generation devices and to determine whether an ultrasound-guided (USG) vs. a fluoroscopy-guided (FG) femoral access management has an impact on their prevention. METHODS This is a prospective, observational, multicenter study. Consecutive patients undergoing TAVR with new-generation devices were analyzed from January 2022 to October 2022 in five tertiary care centers. Femoral accesses were managed according to the operator's preferences. All the patients underwent a pre-discharge peripheral ultrasound control. VCs and bleedings were the main endpoints of interest. RESULTS A total of 458 consecutive patients were enrolled (274 in the USG group and 184 in the FG group). VCs occurred in 6.5 % of the patients (5.2 % minor and 1.3 % major). There was no difference between the USG and the FG groups in terms of any VCs (7.3 % vs. 5.4 %; p = 0.4), or any VARC-3 bleedings (6.9 % vs 6 %, p = 0.9). At logistic regression analysis, the two guidance strategies did not result as predictors of VCs (odds Ratio 0.8, 95 % Confidence Interval 0.46-1.4; P = 0.4). CONCLUSIONS In a contemporary cohort of patients undergoing TAVR with new-generation devices, the occurrence of VCs is low and mostly represented by minor VCs. USG and FG modalities did not affect the rate of VCs.

Abstract
BACKGROUND In the first report from the MitraBridge registry, MitraClip as a bridge to heart transplantation (HTx) proved to be at 1-year an effective treatment strategy for 119 patients with advanced heart failure (HF) who were potential candidates for HTx. We aimed to determine if benefits of MitraClip procedure as a bridge-to-transplant persist up to 2-years. METHODS By the end of the enrollment period, a total of 153 advanced HF patients (median age 59 years, left ventricular ejection fraction 26.9 ± 7.7%) with significant secondary mitral regurgitation, who were potential candidates for HTx and were treated with MitraClip as a bridge-to-transplant strategy, were included in the MitraBridge registry. The primary endpoint was the 2-year composite adverse events rate of all-cause death, first hospitalization for HF, urgent HTx or LVAD implantation. RESULTS Procedural success was achieved in 89.5% of cases. Thirty-day mortality was 0%. At 2-year, Kaplan-Meier estimates of freedom from primary endpoint was 47%. Through 24 months, the annualized rate of HF rehospitalization per patient-year was 44%. After an overall median follow-up time of 26 (9-52) months, elective HTx was successfully performed in 30 cases (21%), 19 patients (13.5%) maintained or obtained the eligibility for transplant, and 32 patients (22.5%) no longer had an indication for HTx because of significant clinical improvement. CONCLUSIONS After 2-years of follow-up, the use of MitraClip as a bridge-to-transplant was confirmed as an effective strategy, allowing elective HTx or eligibility for transplant in one third of patients, and no more need for transplantation in 22.5% of cases.

Transcatheter aortic valve replacement with the self-expanding ACURATE Neo2 in patients with horizontal aorta: Insights from the ITAL-neo registry. Int J Cardiol 2023; 389:131236. [PMID: 37532153 DOI: 10.1016/j.ijcard.2023.131236] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Revised: 07/12/2023] [Accepted: 07/28/2023] [Indexed: 08/04/2023]
Abstract
BACKGROUND Horizontal aorta (HA), defined by an aortic angulation (AA) ≥48°, is associated with worse outcomes particularly after self-expanding (SE) trans-catheter heart valve (THV) implantation. Although the SE ACURATE Neo THV demonstrated favorable procedural success rates in patients with HA, it remains associated with a non-negligible rate of moderate or greater paravalvular leak (PVL). OBJECTIVES Aim of the study was to assess the performance of ACURATE Neo2 in the setting of HA. METHODS We performed a multicenter cohort analysis on patients with severe aortic valve stenosis and HA undergoing transcatheter aortic valve replacement (TAVR) with the Neo or Neo2 THV enrolled in the ITAL-neo registry. The primary endpoint was a composite of early safety and clinical efficacy at 30 days according to the Valve Academic Research Consortium-3 (VARC-3). Secondary endpoints included the occurrence of moderate or severe PVL and 90-day clinical outcomes. RESULTS Among 900 patients included in the ITAL-neo registry, 407 exhibited HA; of these, 300 received a Neo THV and 107 a Neo2 THV. HA, irrespective of the THV implanted, emerged as an independent risk factor for developing ≥ moderate PVL. Technical and device success at 30-day follow-up was comparable between groups. However, Neo2 was associated with a significantly lower rate of ≥moderate PVL vs. Neo: (5% vs. 15%; p < 0.001), which was confirmed also at 90-day follow-up. Additionally, no correlation was found between ≥moderate PVL and AA in the Neo2 group, while PVL degree increased proportionally to the AA in the Neo cohort. CONCLUSION In patients with HA, the new generation Acurate Neo2 THV was associated with a comparable device success rate and a significantly lower rate of ≥moderate PVL, when compared with its predecessor.

Abstract
BACKGROUND The first-generation ACURATE neo transcatheter heart valve (THV) (Boston Scientific) was associated with a non-negligible occurrence of moderate or greater paravalvular aortic regurgitation (AR) following transcatheter aortic valve replacement. To overcome this issue, the ACURATE neo2 iteration, which incorporates a taller outer skirt aimed at reducing the occurrence of paravalvular AR, has recently been developed. OBJECTIVES The aim of this study was to assess the efficacy and safety of the ACURATE neo2 (Boston Scientific) THV in patients with severe aortic valve stenosis. METHODS ITAL-neo was an observational, retrospective, multicenter registry enrolling consecutive patients with severe aortic valve stenosis, treated with first- and second-generation ACURATE neo THVs, via transfemoral and trans-subclavian access, in 13 Italian centers. One-to-one propensity score matching was applied to account for baseline characteristics unbalance. The primary endpoint was the occurrence of moderate or greater paravalvular AR on predischarge echocardiographic assessment. Secondary endpoints included postprocedural technical success and 90-day device success and safety. RESULTS Among 900 patients included in the registry, 220 received the ACURATE neo2 THV, whereas 680 were treated with the first-generation device. A total of 410 patients were compared after 1:1 propensity score matching. The ACURATE neo2 THV was associated with a 3-fold lower frequency of postprocedural moderate or greater paravalvular AR (11.2% vs 3.5%; P < 0.001). No other hemodynamic differences were observed. Postprocedural technical success was similar between the 2 cohorts. Fewer adverse events were observed in patients treated with the ACURATE neo2 at 90 days. CONCLUSIONS Transfemoral transcatheter aortic valve replacement using the ACURATE neo2 was associated with a significant lower frequency of moderate or greater paravalvular AR compared with the earlier generation ACURATE neo device, with encouraging short-term safety and efficacy.

Abstract
Abstract
Aims
Whether patients with spontaneous coronary artery dissection (SCAD) should undergo an initial conservative management or immediate revascularization through percutaneous coronary intervention (PCI) remains debated. To investigate the frequency and predictors of choosing a strategy of immediate PCI for SCAD, and to compare the clinical outcomes of immediate PCI patients with those undergoing an initial strategy of medical management.
Methods and results
369 patients enrolled in the multicentre international DIssezioni Spontanee COronariche (DISCO) registry between January 2009 and December 2020 were included. The primary endpoint was major adverse cardiovascular events (MACE), a composite of cardiac death, non-fatal myocardial infarction (MI) and any PCI. 240 (65%) patients underwent initial medical management, whereas 129 (35%) had immediate PCI. PCI patients presented more frequently with ST segment-elevation myocardial infarction (STEMI) (68.2% vs. 35%, P < 0.001) and had higher frequency of proximal coronary segment SCAD (31.8% vs. 6.7%, P < 0.001), Thrombolysis in Myocardial infarction (TIMI) flow grade 0–1 (54.3% vs. 20.4%, P < 0.001) and multivessel SCAD (18.6% vs. 9.2%, P = 0.015), as well as a more severe diameter stenosis [99% (100–90) vs. 90% (99–75), P < 0.001]. At multivariate logistic regression, STEMI at presentation (vs. NSTE-ACS, OR: 3.30 95% CI: 1.56–7.12, P = 0.002), proximal coronary segment involvement (OR: 5.43, 95% CI: 1.98–16.45, P = 0.002), TIMI flow grade 0–1 and 2 (respectively, vs. grade 3: OR: 3.22 95% CI: 1.08–9.96, P = 0.038; and OR: 3.98; 95% CI: 1.38–11.80, P = 0.009) and diameter stenosis (per 5% increase, OR: 1.13; 95% CI: 1.01–1.28, P = 0.037) were predictors of immediate PCI, whereas the angiographic subtype 2B predicted a conservative approach (OR: 0.25; 95% CI: 0.07–0.83, P = 0.026). The frequency of in-hospital major adverse cardiac events did not differ between medically and PCI-treated patients. At 2-year follow-up, there were no differences with respect to the composite of MACE (11.7% vs. 13.9%, P = 0.47) and the individual components of cardiovascular death (0.4% vs. 0.7%, P = 0.65), non-fatal MI (8.3% vs. 9.3%, P = 0.92), and any PCI (8.7% vs. 12.4%, P = 0.23).
Conclusions
The choice between an immediate medical or PCI management of SCAD is mostly driven by clinical presentation and procedural aspects. In the DISCO cohort, the primary treatment approach was not associated with the risk of short-to-midterm adverse events.

Abstract
BACKGROUND Coronavirus disease 2019 (COVID-19) has shown high morbidity and mortality and the relationship between pulmonary embolism (PE) and COVID-19 is well established in the literature. METHODS We describe the characteristics of a cohort of COVID-19 patients (EP-COV) hospitalized at our Centre with PE, investigating how COVID-19 may have influenced their outcomes, as compared to patients without COVID-19 hospitalized for PE in the same months of 2020 (EP-2020) and 2019 (EP-2019). RESULTS EP-COV patients (n=25) were younger (60.5 ± 8.5 vs 71.4 ± 14.5 vs 70.9 ± 11.8 years, p=0.003), more frequently male (76% vs 48% vs 35%, p=0.016), with a lower history of neoplasia (12% vs 47% vs 40%, p=0.028) and more clinically severe (SOFA score 3.4 ± 1.4 vs 2.2 ± 1.4 vs 1 ± 1.1, p<0.001 and PaO2/FiO2 ratio 223.8 ± 75.5 vs 306.5 ± 49.3 vs 311.8 ± 107.5) than EP-2020 (n=17) and EP-2019 patients (n=20). D-dimer and C-reactive protein were higher in EP-COV (p=0.038 e p<0.001, respectively). The rate of concomitant deep vein thrombosis associated with PE did not differ significantly between the three groups. EP-COV patients developed PE more frequently during in-hospital stay than non-COVID-19 patients (p = 0.016). The mortality rate was higher in EP-COV than in EP-2020 and EP-2019 patients (36% vs 0% vs 5%, p=0.019). CONCLUSIONS In our study, the risk factors for PE in COVID-19 patients seem to differ from the traditional risk factors for venous thromboembolism; EP-COV patients are clinically more severe and display a higher mortality rate than EP-2020 and EP-2019 patients.

Abstract
BACKGROUND Spontaneous coronary artery dissection (SCAD) is an increasingly diagnosed cause of myocardial infarction. Although different SCAD angiographic classifications exist, their clinical impact remains unknown. AIMS The aim of this study was to evaluate the relationship between an angiographic classification and the development of adverse clinical events during the follow-up of a large, unselected cohort of patients with SCAD. METHODS We conducted an observational study of consecutive SCAD patients from 26 centres across Italy and Spain. Cases were classified into five different angiotypes according to the latest classification endorsed by the European Society of Cardiology. The main composite endpoint included all-cause death, non-fatal myocardial infarction (MI), and any unplanned revascularisation. RESULTS In total, 302 SCAD patients (mean age 51.8±19 years) were followed up for a median of 22 months (IQR 12-48). At 28 days, the composite outcome was higher for the angiotypes with a circumscribed contained intramural haematoma (2A and 3): 20.0% vs 5.4%, p<0.001 (non-fatal MI: 11.0% vs 3.5%, p=0.009; unplanned revascularisation: 11.0% vs 2.5%, p<0.001). This was sustained during follow-up (24.5% vs 9.9%, p=0.001). There were no differences in mortality (0.3% overall). The presence of an angiotype 2A or 3 was an independent predictor of a higher incidence of the composite outcome (adjusted HR 2.44, CI: 1.24-4.80, p=0.010). CONCLUSIONS The SCAD angiographic classification correlates with outcome. Those presenting with an angiographically circumscribed contained intramural haematoma (angiotypes 2A and 3) showed an increased risk of short-term adverse clinical events that was maintained during follow-up.

Abstract
AIMS The role of antiplatelet therapy in patients with spontaneous coronary artery dissection (SCAD) undergoing initial conservative management is still a matter of debate, with theoretical arguments in favour and against its use. The aims of this article are to assess the use of antiplatelet drugs in medically treated SCAD patients and to investigate the relationship between single (SAPT) and dual (DAPT) antiplatelet regimens and 1-year patient outcomes. METHODS AND RESULTS We investigated the 1-year outcome of patients with SCAD managed with initial conservative treatment included in the DIssezioni Spontanee COronariche (DISCO) multicentre international registry. Patients were divided into two groups according to SAPT or DAPT prescription. Primary endpoint was 12-month incidence of major adverse cardiovascular events (MACE) defined as the composite of all-cause death, non-fatal myocardial infarction (MI), and any unplanned percutaneous coronary intervention (PCI). Out of 314 patients included in the DISCO registry, we investigated 199 patients in whom SCAD was managed conservatively. Most patients were female (89%), presented with acute coronary syndrome (92%) and mean age was 52.3 ± 9.3 years. Sixty-seven (33.7%) were given SAPT whereas 132 (66.3%) with DAPT. Aspirin plus either clopidogrel or ticagrelor were prescribed in 62.9% and 36.4% of DAPT patients, respectively. Overall, a 14.6% MACE rate was observed at 12 months of follow-up. Patients treated with DAPT had a significantly higher MACE rate than those with SAPT [18.9% vs. 6.0% hazard ratios (HR) 2.62; 95% confidence intervals (CI) 1.22-5.61; P = 0.013], driven by an early excess of non-fatal MI or unplanned PCI. At multiple regression analysis, type 2a SCAD (OR: 3.69; 95% CI 1.41-9.61; P = 0.007) and DAPT regimen (OR: 4.54; 95% CI 1.31-14.28; P = 0.016) resulted independently associated with a higher risk of 12-month MACE. CONCLUSIONS In this European registry, most patients with SCAD undergoing initial conservative management received DAPT. Yet, at 1-year follow-up, DAPT, as compared with SAPT, was independently associated with a higher rate of adverse cardiovascular events (ClinicalTrial.gov id: NCT04415762).

Abstract
Preserving coronary artery access is a crucial goal during transcatheter aortic valve replacement (TAVR) procedures, especially in case of self-expandable transcatheter heart valve (SE-THV) implantation. In this light, a proper commissural alignment is needed to avoid the risk of coronary obstruction and to permit easy vessels re-cannulation for diagnostic and interventional purposes. New-generation SE-THVs have been furnished of different markers, able to guide operators to perform a correct commissural alignment. In this case series, we describe key procedural aspects of commissural alignment for the different available SE-THVs, providing a step-by-step tutorial for each device. Lastly, we illustrate a commissural alignment in a contrast-zero TAVR.

Abstract
We report a translational experience of a cardiovascular department facing MACE in COVID-19 patients. Acute arterial events are the real emergency into this COVID-19 pandemic. COVID-19 infection may trigger a hypercoagulable status leading to MACE and high mortality rate. In this COVID-19 outbreak, the adjunct of heparin provides better survival chance independently of the infection-related drug treatment.

Abstract
Objectives: To present a single-centre experience on CT pulmonary angiography (CTPA) for the assessment of hospitalised COVID-19 patients with moderate-to-high risk of pulmonary thromboembolism (PTE). Methods: We analysed consecutive COVID-19 patients (RT-PCR confirmed) undergoing CTPA in March 2020 for PTE clinical suspicion. Clinical data were retrieved. Two experienced radiologists reviewed CTPAs to assess pulmonary parenchyma and vascular findings. Results: Among 34 patients who underwent CTPA, 26 had PTE (76%, 20 males, median age 61 years, interquartile range 54–70), 20/26 (77%) with comorbidities (mainly hypertension, 44%), and 8 (31%) subsequently dying. Eight PTE patients were under thromboprophylaxis with low-molecular-weight heparin, four PTE patients had lower-limbs deep vein thrombosis at ultrasound examination (performed in 33/34 patients). Bilateral PTE characterised 19/26 cases, with main branches involved in 10/26 cases. Twelve patients had a parenchymal involvement >75%, the predominant pneumonia pattern being consolidation in 10/26 patients, ground glass opacities in 9/26, crazy paving in 5/26, and both ground glass opacities and consolidation in 2/26. Conclusion: COVID-19 patients are prone to PTE. Advances in knowledge: PTE, potentially attributable to an underlying thrombophilic status, may be more frequent than expected in COVID-19 patients. Extension of prophylaxis and adaptation of diagnostic criteria should be considered.

Abstract
AIM Galectin-3 (Gal-3), a biomarker of inflammation, tissue repair and fibrogenesis, is associated to left ventricular remodeling after ST-elevated myocardial infarction (STEMI), but its relation with long-term outcomes is unclear. METHODS In 103 consecutive patients with a first anterior STEMI treated by primary angioplasty, we assayed Gal-3 and NT-proBNP. RESULTS Age was 65 (56-76) years, 28% were women. During 18 ± 13 months, 20 patients (19.4%) died or were admitted for heart failure. After adjustment for age, gender, renal and ventricular function, troponin, NT-proBNP and Gal-3 independently predicted the combined end point (hazard ratio: 1.11; 95% CI: 1.05-1.17; per 1 ng/ml increase). Event-free survival was 42.3 versus 93.5% for Gal-3≥ versus <16.8 ng/ml (p < 0.001). CONCLUSION Among anterior STEMI patients, early postangioplasty Gal-3 levels may be useful for risk stratification.

Abstract
OBJECTIVES To first explore in Italy appropriateness of indication, adherence to guideline recommendations and mode of selection for coronary revascularisation. DESIGN Retrospective, pilot study. SETTING 22 percutaneous coronary intervention (PCI)-performing hospitals (20 patients per site), 13 (59%) with on-site cardiac surgery. PARTICIPANTS 440 patients who received PCI for stable coronary artery disease (CAD) or non-ST elevation acute coronary syndrome were independently selected in a 4:1 ratio with half diabetics. PRIMARY AND SECONDARY OUTCOME MEASURES Proportion of patients who received appropriate PCI using validated appropriate use scores (ie, AUS≥7). Also, in patients with stable CAD, we examined adherence to the following European Society of Cardiology recommendations: (A) per cent of patients with complex coronary anatomy treated after heart team discussion; (B) per cent of fractional flow reserve-guided PCI for borderline stenoses in patients without documented ischaemia; (C) per cent of patients receiving guideline-directed medical therapy at the time of PCI as well as use of provocative test of ischaemia according to pretest probability (PTP) of CAD. RESULTS Of the 401 mappable PCIs (91%), 38.7% (95% CI 33.9 to 43.6) were classified as appropriate, 47.6% (95% CI 42.7 to 52.6) as uncertain and 13.7% (95% CI 10.5% to 17.5%) as inappropriate. Median PTP in patients with stable CAD without known coronary anatomy was 69% (78% intermediate PTP, 22% high PTP). Ischaemia testing use was similar (p=0.71) in patients with intermediate (n=140, 63%) and with high PTP (n=40, 66%). In patients with stable CAD (n=352) guideline adherence to the three recommendations explored was: (A) 11%; (B) 25%; (C) 23%. AUS was higher in patients evaluated by the heart team as compared with patients who were not (7 (6.8) vs 5 (4.7); p=0.001). CONCLUSIONS Use of heart team approaches and adherence to guideline recommendations on coronary revascularisation in a real-world setting is limited. This pilot study documents the feasibility of measuring appropriateness and guideline adherence in clinical practice and identifies substantial opportunities for quality improvement. TRIAL REGISTRATION NUMBER NCT02748603.

Targeting N-Terminal Pro-Brain Natriuretic Peptide in Older Versus Younger Acute Decompensated Heart Failure Patients. JACC-HEART FAILURE 2016; 4:736-45.

Abstract
OBJECTIVES The aim of this study was to analyze the prognostic value and attainability of N-terminal pro-brain natriuretic peptide (NT-proBNP) levels in young and elderly acute decompensated heart failure (ADHF) patients. BACKGROUND Less-effective NT-proBNP-guided therapy in chronic heart failure (HF) has been reported in elderly patients. Whether this can be attributed to differences in prognostic value of NT-proBNP or to differences in attaining a prognostic value is unclear. The authors studied this question in ADHF patients. METHODS Our study population comprised 7 ADHF cohorts. We defined absolute (<1,500 ng/l, <3,000 ng/l, <5,000 ng/l, and <15,000 ng/l) and relative NT-proBNP discharge cut-off levels (>30%, >50%, and >70%). Six-month all-cause mortality after discharge was studied for each level in Cox regression analyses, and compared between elderly (age >75 years) and young patients (age ≤75 years). Thereafter, we compared percentages of elderly and young patients attaining NT-proBNP levels (= attainability). RESULTS A total of 1,235 patients (59% male, 45% >75 years of age) was studied. Admission levels of NT-proBNP were significantly higher in elderly versus younger patients. The prognostic value of absolute and relative NT-proBNP levels was similar in elderly and young patients. Attainability was significantly lower in elderly patients for all absolute levels and a >50% relative reduction, but not for >30% and >70%. For absolute levels, attainability differences between age groups were decreased to a large extent after correction for admission NT-proBNP and anemia at discharge. For relative levels, attainability differences disappeared after correction for HF etiology and anemia at discharge. CONCLUSIONS In young and elderly ADHF patients, it is not the prognostic value of absolute and relative NT-proBNP levels that is different, but the attainability of these levels that is lower in the elderly. This can largely be attributed to factors other than age.

Abstract
Aims AUGMENT-HF was an international, multi-centre, prospective, randomized, controlled trial to evaluate the benefits and safety of a novel method of left ventricular (LV) modification with alginate-hydrogel. Methods Alginate-hydrogel is an inert permanent implant that is directly injected into LV heart muscle and serves as a prosthetic scaffold to modify the shape and size of the dilated LV. Patients with advanced chronic heart failure (HF) were randomized (1 : 1) to alginate-hydrogel (n = 40) in combination with standard medical therapy or standard medical therapy alone (Control, n = 38). The primary endpoint of AUGMENT-HF was the change in peak VO2 from baseline to 6 months. Secondary endpoints included changes in 6-min walk test (6MWT) distance and New York Heart Association (NYHA) functional class, as well as assessments of procedural safety. Results Enrolled patients were 63 ± 10 years old, 74% in NYHA functional class III, had a LV ejection fraction of 26 ± 5% and a mean peak VO2 of 12.2 ± 1.8 mL/kg/min. Thirty-five patients were successfully treated with alginate-hydrogel injections through a limited left thoracotomy approach without device-related complications; the 30-day surgical mortality was 8.6% (3 deaths). Alginate-hydrogel treatment was associated with improved peak VO2 at 6 months—treatment effect vs. Control: +1.24 mL/kg/min (95% confidence interval 0.26–2.23, P = 0.014). Also 6MWT distance and NYHA functional class improved in alginate-hydrogel-treated patients vs. Control (both P < 0.001). Conclusion Alginate-hydrogel in addition to standard medical therapy for patients with advanced chronic HF was more effective than standard medical therapy alone for improving exercise capacity and symptoms. The results of AUGMENT-HF provide proof of concept for a pivotal trial. Trial Registration Number NCT01311791.

Abstract
BACKGROUND Models to stratify risk for patients hospitalised for acute decompensated heart failure (ADHF) do not include the change in N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels during hospitalisation. OBJECTIVE The aim of our study was to develop a simple yet robust discharge prognostication score including NT-proBNP for this notorious high-risk population. DESIGN Individual patient data meta-analyses of prospective cohort studies. SETTING Seven prospective cohorts with in total 1301 patients. PATIENTS Our study population was assembled from the seven studies by selecting those patients admitted because of clinically validated ADHF, discharged alive, and NT-proBNP measurements available at admission and at discharge. MAIN OUTCOME MEASURES The endpoints studied were all-cause mortality and a composite of all-cause mortality and/or first readmission for cardiovascular reason within 180 days after discharge. RESULTS The model that incorporated NT-proBNP levels at discharge as well as the changes in NT-proBNP during hospitalisation in addition to age ≥75 years, peripheral oedema, systolic blood pressure ≤115 mm Hg, hyponatremia at admission, serum urea of ≥15 mmol/L and New York Heart Association (NYHA) class at discharge, yielded the best C-statistic (area under the curve, 0.78, 95% CI 0.74 to 0.82). The addition of NT-proBNP to a reference model significantly improved prediction of mortality as shown by the net reclassification improvement (62%, p<0.001). A simplified model was obtained from the final Cox regression model by assigning weights to individual risk markers proportional to their relative risks. The risk score we designed identified four clinically significant subgroups. The pattern of increasing event rates with increasing score was confirmed in the validation group (BOT-AcuteHF, n=325, p<0.001). CONCLUSIONS In patients hospitalised for ADHF, the addition of the discharge NT-proBNP values as well as the change in NT-proBNP to known risk markers, generates a relatively simple yet robust discharge risk score that importantly improves the prediction of adverse events.

Abstract
Renal dysfunction is often present and/or worsens in patients with heart failure and this is associated with increased costs of care, complications and mortality. The cardiorenal syndrome can be defined as the presence or development of renal dysfunction in patients with heart failure. Its mechanisms are likely related to low cardiac output, increased venous congestion and renal venous pressure, neurohormonal and inflammatory activation and local changes, such as adenosine release. Many drugs, including loop diuretics, may contribute to worsening renal function through the activation of some of these mechanisms. Renal damage is conventionally defined by the increase in creatinine and blood urea nitrogen blood levels. However, these changes may be not related with renal injury or prognosis. New biomarkers of renal injury seem promising but still need to be validated. Thus, despite the epidemiological evidence, we are still lacking of satisfactory tools to assess renal injury and function and its prognostic significance.

Abstract
Heart failure is one of the most common, costly, disabling and growing diseases (McMurray and Pfeffer in Lancet 365(9474):1877-1889, 2005). Hyponatremia, conventionally defined as a serum-sodium concentration equal or less than 135 mmol/l (American Heart Association in Heart disease and stroke statistics--2007 update. American Heart Association, Dallas, 2007; Stewart et al. in Eur J Heart Fail 4:361-371, 2002), is a common phenomenon in patients with heart failure, with an incidence of 20-25% (Krumholz et al. in Arch Intern Med 157:e99-e104, 1997; Rosamond et al. in Circulation 117(4):e25-e146, 2008; Adrogue and Madias in N Engl J Med 342:1581-1589, 2000) and seems to be of prognostic importance in patients with heart failure (Luca et al. in Am J Cardiol 96:19L-23L, 2005; Gheorghiade et al. in Eur Heart J 28:980-988, 2007; Gheorghiade et al. in Arch Intern Med 167:1998-2005, 2007). So far treatment strategies have been limited and burdened by side effects. The development of hyponatremia in the setting of heart failure is related to the arginine vasopressin (AVP) dysregulation. Thus, AVP receptor antagonists are a promising approach to treatment. However, several questions remain: whether there is a cause-and-effect mechanism, if the correction of hyponatremia improves outcomes, and defining the specific cut-off level of serum-sodium that should be used to define hyponatremia. In this review, we aim to summarize the literature on hyponatremia in patients with heart failure within several aspects: incidence in clinical trials and registries, prognostic value, underlying mechanisms, therapeutic options, and possible future perspectives.

Abstract
Despite the epidemiologic importance, large investments, and careful design, recent results of heart failure (HF) trials have been unable to demonstrate significant treatment improvements. This shortcoming has led to a reassessment of research methodology, particularly related to sample size and costs, for which end-point selection is a main issue. In comparing interventions in clinical trials, surrogate end points may be used to reduce the costs. To this end, ongoing research into the roles of imaging biomarkers as reliable surrogate end points may lead to better clinical trial design and more efficient development of new therapies for HF.

Abstract
BACKGROUND Worsening renal function (WRF), traditionally defined as an increase in serum creatinine levels ≥0.3 mg/dL, is a frequent finding in patients with acute heart failure (AHF) and has been associated with poorer outcomes in some but not all studies. We hypothesized that these discrepancies may be caused by the interaction between WRF and congestion in AHF patients. METHODS AND RESULTS We measured serum creatinine levels on a daily basis during the hospitalization and assessed the persistence of signs of congestion at discharge in 599 consecutive patients admitted at our institute for AHF. They had a postdischarge mortality and mortality or AHF readmission rates of 13% and 43%, respectively, after 1 year. Patients were subdivided into 4 groups according to the development or not of WRF and the persistence of ≥1 sign of congestion at discharge. Patients with WRF and no congestion had similar outcomes compared with those with no WRF and no congestion, whereas the risk of death or of death or AHF readmission was increased in the patients with persistent congestion alone and in those with both WRF and congestion (hazard ratio, 5.35; 95% confidence interval, 3.0-9.55 at univariable analysis; hazard ratio, 2.44; 95% confidence interval, 1.24-4.18 at multivariable analysis for mortality; hazard ratio, 2.14; 95% confidence interval, 1.39-3.3 at univariable analysis; and hazard ratio, 1.39; 95% confidence interval, 0.88-2.2 at multivariable analysis for mortality and rehospitalizations). CONCLUSIONS WRF alone, when detected using serial serum creatinine measurements, is not an independent determinant of outcomes in patients with AHF. It has an additive prognostic value when it occurs in patients with persistent signs of congestion.

Abstract
Inotropic agents are administered to improve cardiac output and peripheral perfusion in patients with systolic dysfunction and low cardiac output. However, there is evidence of increased mortality and adverse effects associated with current inotropic agents. These adverse outcomes may be ascribed to patient selection, increased myocardial energy expenditure and oxygen consumption, or to specific mechanisms of action. Both sympathomimetic amines and type III phosphodiesterase inhibitors act through an increase in intracellular cyclic adenosine monophoshate and free calcium concentrations, mechanisms that increase oxygen consumption and favor arrhythmias. Concomitant peripheral vasodilation with some agents (phosphodiesterase inhibitors and levosimendan) may also lower coronary perfusion pressure and favor myocardial damage. New agents with different mechanisms of action might have a better benefit to risk ratio and allow an improvement in tissue and end-organ perfusion with less untoward effects. We have summarized the characteristics of the main inotropic agents for heart failure treatment, the data from randomized controlled trials, and future perspectives for this class of drugs.

Abstract
BACKGROUND Galectin-3 is a soluble ß-galactoside-binding lectin released by activated cardiac macrophages. Elevated levels of galectin-3 have been found to be associated with adverse outcomes in patients with heart failure. We evaluated the association between galectin-3 and long-term clinical outcomes in ambulatory heart failure patients enrolled in the HF-ACTION study. METHODS AND RESULTS HF-ACTION was a randomized, controlled trial of exercise training in patients with chronic heart failure caused by left ventricular systolic dysfunction. Galectin-3 was assessed at baseline in a cohort of 895 HF-ACTION subjects with stored plasma samples available. The association between galectin-3 and clinical outcomes was assessed using a series of Cox proportional hazards models. Higher galectin-3 levels were associated with other measures of heart failure severity, including higher New York Heart Association class, lower systolic blood pressure, higher creatinine, higher amino-terminal proB-type natriuretic peptide (NTproBNP), and lower maximal oxygen consumption. In unadjusted analysis, there was a significant association between elevated galectin-3 levels and hospitalization-free survival (unadjusted hazard ratio, 1.14 per 3-ng/mL increase in galectin-3; P<0.0001). In multivariable modeling, the prognostic impact of galectin-3 was significantly attenuated by the inclusion of other known predictors, and galectin-3 was no longer a significant predictor after the inclusion of NTproBNP. CONCLUSIONS Galectin-3 is elevated in ambulatory heart failure patients and is associated with poor functional capacity and other known measures of heart failure severity. In univariate analysis, galectin-3 was significantly predictive of long-term outcomes, but this association did not persist after adjustment for other predictors, especially NTproBNP.

Abstract
Abnormalities of cardiac function, with high intraventricular filling pressure and low cardiac output, play a central role in patients with heart failure. Agents with inotropic properties are potentially useful to correct these abnormalities. However, with the exception of digoxin, no inotropic agent has been associated with favourable effects on outcomes. This is likely related to the mechanism of action of current agents, which is based on an increase in intracellular cyclic adenosine monophosphate and calcium concentrations. Novel agents acting through different mechanisms, such as sarcoplasmic reticulum calcium uptake, cardiac myosin and myocardial metabolism, have the potential to improve myocardial efficiency and lower myocardial oxygen consumption. These characteristics might allow a haemodynamic improvement in the absence of untoward effects on the clinical course and prognosis of the patients.

Abstract
INTRODUCTION Dyspnoea and peripheral oedema, caused by fluid redistribution to the lungs and/or by fluid overload, are the main causes of hospitalization in patients with heart failure and are associated with poor outcomes. Treatment of fluid overload should relieve symptoms and have a neutral or favorable effect on outcomes. AREAS COVERED We first consider the results obtained with furosemide administration, which is still the mainstay of treatment of congestion in patients with heart failure. We then discuss important shortcomings of furosemide treatment, including the development of resistance and side effects (electrolyte abnormalities, neurohormonal activation, worsening renal function), as well as the relationship of furosemide - and its doses - with patient prognosis. Finally, the results obtained with potential alternatives to furosemide treatment, including different modalities of loop diuretic administration, combined diuretic therapy, dopamine, inotropic agents, ultrafiltration, natriuretic peptides, vasopressin and adenosine antagonists, are discussed. EXPERT OPINION Relief of congestion is a major objective of heart failure treatment but therapy remains based on the administration of furosemide, an agent that is often not effective and is associated with poor outcomes. The results of the few controlled studies aimed at the assessment of new treatments to overcome resistance to furosemide and/or to protect the kidney from its untoward effects have been mostly neutral. Better treatment of congestion in heart failure remains a major unmet need.

Abstract
Hospitalizations for acute heart failure are associated with high mortality and readmission rates. Ten to 20% of the patients have signs of low cardiac output and fluid overload. The administration of inotropic agents to correct these hemodynamic abnormalities may be indicated in these patients. However, the risk to benefit ratio of inotropic agents is high and an increase of untoward effects and mortality has been suggested by many retrospective analyses and meta-analyses. Limitations of inotropic therapy seem mainly related to their mechanisms of action based, in the case of the traditional agents, on an increase in intracellular cyclic AMP and calcium concentrations. Concomitant peripheral vasodilation, such as in the case of the novel agent levosimendan is another important limitation, above when patients are hypotensive and/or treated with vasodilators and high doses of diuretics. Myosin activators, histaroxime, sarcoplasmic reticulum ATPase activators and metabolic agents seem promising as active through different mechanisms than traditional agents and, in many cases, not associated with tachycardia or hypotension. Further studies are, however, needed.

Abstract
Acute heart failure (HF) is the most common diagnosis at discharge in patients aged >65years. It carries a dismal prognosis with a high in-hospital mortality and very high post-discharge mortality and re-hospitalization rates. It is a complex clinical syndrome that cannot be described as a single entity as it varies widely with respect to underlying pathophysiologic mechanisms, clinical presentations and, likely, treatments. It is the aim of this paper to describe some of the main clinical presentations of acute HF. Amongst them, we will consider de novo HF versus acutely decompensated chronic HF, HF caused, and/or worsened, by myocardial ischemia, acute HF with low, normal, or high systolic blood pressure, acute HF caused by lung congestion or fluid retention or fluid redistribution to the lungs, and acute HF with comorbidities (diabetes, anemia, renal insufficiency, etc.). Different pathophysiologic mechanisms and clinical presentations may coexist in the same patient. Identification and, whenever possible, treatment of underlying pathophysiologic mechanisms may become important for acute HF management.

Abstract
Hospitalization for acute heart failure (AHF) is one of the burdensome aspects of 21st century medicine, leading to significant debilitating symptoms, high morbidity and mortality and consuming significant portion of the health care budget. Management of AHF is thought-provoking given the heterogeneity of the patient population, absence of a universally accepted definition, incomplete understanding of the pathophysiology and the beneficial and adverse effects of currently used therapies and lack of robust evidence-based guidelines. The article will discuss the clinical approach to the patients admitted with AHF, reviewing types of intervention (both approved and investigational) and will delineate their role and timing in specific AHF presentations. One of the challenges of AHF management is to effectively treat the subsets of patients with slow improvement or those with refractory AHF or early recurrence (worsening HF) during their initial admission. Unfortunately, the majority of these patients are at increased risk for subsequent complications and adverse outcomes. Therefore, considerable efforts in AHF management should be directed towards this population. Regretfully, to date no specific targeted therapy was proven beneficial for these patients, being one of the leading reasons for the lack of improvement in AHF outcomes over the last 30 years.
